Description

12 Volt dual fan MosFet Pulse Width Modulation control. Unit Checks engine temperature and AC Request to determine what fan needs to be on and how fast that fan should be driven. The controller turns the fans on slowly up to 60 percent or 100 percent based on need. It also drives an output Mosfet to truck the Analog temperature gauge in the vehicle to read the correct temperature of the engine. The output comes off of R11. The Arduino Microcontroller also looks at four input lines from the transmission range selector. Based on that input it displays the correct gear on the Serial driven LCD 4x20 Display.
